Water Quality Reports

Willows Water District is a distributor of Denver Water. For more than 85 years Denver Water has supplied fresh, safe water to our customers. We safeguard our mountain water supplies and, before the water reaches your tap, our chemists and biologists sample and test Denver's water every day to make sure it meets the highest state and federal standards for safety and quality.

Denver tests the water before it goes into their treatment plants and again when it comes out, and 130 times more at sampling stations throughout our distribution system.

Periodically, even during drought, Willows will flush the water mains to maintain water quality and ensure fire safety.
